Rayquaza @ Choice Specs / Choice Scarf
Timid Nature,(+Spe,-Atk) or Naive Nature,(+Spe,-SDef) or Modest Nature(+SpA,-Atk) or Naughty Nature(+SAtk,-SDef)
4 HP / 252 Spe / 252 SAtk
-Draco Meteor / Extremespeed
-Fire Blast / Extremespeed
-Ice Beam / Extremespeed
-Thunder / Thunderbolt / Extremespeed
Specs:
The surprise factor in this SpecsQuaza is what really this set is all about.Draco Meteor takes down the most common switch in to Rayquaza effectively(the most common switch in,in my experience,is Dragon Claw Groudon,trying to take Rayquza down with it).Fire Blast hits Scizor and effectively OHKOs in the rain,and the same goes for Forretress.Hidden Power Ice is for hitting Garchomp and other Rayquazas,though most likely you will get revenge killed by Scarfed variants.Extremespeed is an option over it;as it grants you the ability to revenge kill;though it does not deal that much damage as compared to one Swords Dance Extremespeed.Thunder allows you to OHKO Kyogre in the rain(Standard Specs,locked into Water Spout/Surf),without any problem,but if you do not want to rely on the rain to hit other pokemon such as Lugia for Super Effective damage,Thunderbolt is an effective and a reliable choice as well.Extremespeed can also be placed over here if you are not worried about Kyogre or Lugia ruining your fun.Rayquaza can learn Ice Beam and its better than HP Ice.
Scarf:
With a Scarf,Rayquaza effectively outspeeds all Latiases,Latioses,Specs Skymin,Scarf Ogre who run a neutral nature(bar Scarfers),and when you run a +Spe nature,effectively outspeeding Adamant Scarf Chomp.Draco Meteor hits Latias,Latios and ScarfChomp for SE damage,KOing them,besides Latias,who survives with its monstrous base Special Defense.Specs Skymin gets OHKOed by Hidden Power Ice.Scarf Ogre gets hit by a SE Thunder,2HKOing.ScarfQuaza also acts as a surprise factor alongst with Specs Quaza,but unfortunately,Fire Blast fails to OHKO Forry/Scizor in the rain.Rayquaza has only a chance to take down the bulkiest of Groudons with Draco Meteor(Careful,252 HP / 252 SDef),without the Specs.This ScarfQuaza also effectively works as a revenge killer;though physical options are also viable alongside the special options.But the special options deserve more mention as they work as a surprise,AND even more surprising when Rayquaza outspeeds its counters.Take note that Rayquaza fails to outspeed Adamant ScarfChomp or other ScarfQuazas if you run Modest over Timid;you will tie with all the abovementioned bar ScarfOgre,whom you still outspeed.If Skymin runs Scarf,you lose to it as well.Rayquaza outspeeds base 150s without a Scarf,as it reaches 470 Speed,whereas the base 150s reach 438 Speed.(EDIT: You can also outspeed ScarfKia and ScarfLga.ScarfKia can only be outsped if they do not run a +Spe nature,otherwise you tie with it.ScarfLga is outspeed no matter which nature it runs.
Other options in this set include:
-Hidden Power Grass,to take down Swampert
-Outrage,as a plan for Blissey(in various stall teams)
-All the other physical options Rayquaza has for the Scarfed Set.
SubFlinch Jirachi
Jirachi @ Leftovers
Adamant Nature,or Jolly Nature,or Naive Nature
252 HP / 252 Atk / 4 Def
-Substitute
-Iron Head
-Thunder Wave
-Ice Punch / Thunder Punch / Grass Knot / Fire Punch
If you think that Iron Head + TWave is annoying enough,thin again.With a Substitute,the opponent literally has a very low chance of trying to kill you and prevents you from the prominent statuses in today's metagame.With Substitute,Jirachi also has more chances to scout and paralyze or hit accordingly with TWave or its moves.Substitute and Thunder Wave are obvious choices in this moveset as they are the centre of this moveset.Iron Head is an obligatory move as well.The last slot has many options;but these four options are the best.The elemental punches hit the dragons,bulky waters,and steels respectively,who Iron Head sometimes fail to hit.Although Ice Punch may seem redundant,it helps you OHKO Salamence after -1 Attack from Intimidate.Thunder Punch hits Gyarados,Milotic,Suicune who resist Iron Head.Ironically,it also OHKOs Gyarados after -1 Attack from Intimidate.Grass Knot hits Swampert,OHKOing it,without any SpA EVs,and it turns Jirachi into a mixed Subber.Fire Punch hits Scizor for SE damage,who resists the first four moves mentioned,bar Thunder Punch.Other options here include Wish,since you may want recovery as Substitute is draining your health rapidly.Body Slam can be used over Thunder Wave to paralyze the ground types,but Thunder Wave is generally a better choice for the 100% paralysis,rather than Body Slam's 60%.Jirachi can also run Shadow Ball to take down the Rotom appliances,most notably Rotom-h,who run Overheat.U-Turn is also an option here,to allow your stat up sweepers to set up,after you paralyze the opponent's pokemons.Generally,this Jirachi set is suited to fit your team's needs.Jirachi effectively survives one +1 DDed Earthquake from Salamence/Gyarados with the EVs.No Speed EVs were put as Jirachi literally outspeeds everything after paralysis support.
SalacTwo
Mewtwo @ Salac Berry
Timid Nature,or Modest Nature
4 Def / 252 Spe / 252 SAtk
-Substitute / Calm Mind
-Recover
-Ice Beam
-Thunder / Thunderbolt / Aura Sphere
Effectively as it can be at sweeping,this set utilizes its ability to outspeed ALL Deoxys-s formes after one Salac boost.With the Salac boost,and Timid Nature,Mewtwo reaches 591 Speed(which,outspeeds all Scarfed base 130s if I remember correctly).Otherwise,538 Speed with a Modest nature.Recover allows Mewtwo to restore HP after Subbing to 25% HP,activating the Salac.Calm Mind can be put over Substitute though;as Mewtwo generally has enough bulk to survive one attack from a pokemon,with a little bit of HP,thus still activating the Salac WITH one CM boost.Ice Beam and Thunder provides Mewtwo with the infamous BoltBeam coverage,though Thunderbolt can be used over Thunder,but the significant drop in power really hurts Mewtwo.Mewtwo will activate its Salac Berry effectively after 3 Substitutes,with 25% HP.But,for this to work without any problems,Mewtwo's greatest counter has to be defeated before it is sent in.Scizor has to be eliminated.After 3 Subs,Mewtwo gets OHKOed by Bullet Punch,without any SD boosts.Mewtwo also faces some trouble against Whirlwind Lugias,who seem to be decreasing in usage nowadays.Even if it comes out,a +1 Thunder can effectively OHKO Bold Nature,standard spread.(252 Def / 4 HP / 252 Spe).Otherwise,a +2 Thunder OHKOs the 252 Def / 252 HP / 4 SDef variant.+4 Thunder OHKOs the 252 HP / 252 SDef / 4 Def variant.Ice Beam OHKOs Giratina after one CM boost as it survives one Shadow Ball after one CM.Ice Beam OHKOs Rayquaza before a CM boost,whilst a +0 Extremespeed does not OHKO,even after 2 switch ins after SR.Options here include Grass Knot,to hit Kyogre and Groudon,but Ice Beam and Thunder are generally better.I have completely forgotten about Blissey in the Uber Stall teams,thus you can run Aura Sphere over something,Thunder maybe.
